  "message": "c++: Fix ICE during explanation of failed __has_unique_object_representation [PR126867]\n\nThe following testcase ICEs since r16-5520 added explain\narguments to type_has_unique_obj_representations and\nrecord_has_unique_obj_representations.  Most of the location_t\narguments in that change look correct, either DECL_SOURCE_LOCATION\nof some FIELD_DECL or in type_has_unique_obj_representations use\nloc, which is initialized to\n  location_t loc \u003d input_location;\n  if (tree m \u003d TYPE_MAIN_DECL (t))\n    loc \u003d DECL_SOURCE_LOCATION (m);\nBut in record_has_unique_obj_representations we don\u0027t have\na variable like that and t at that point is the RECORD_TYPE\nor UNION_TYPE, so using DECL_SOURCE_LOCATION on it will surely ICE\nin a checking compiler.\nlocation_of call does the above dances, so it seems easiest to\ncall it rather than duplicate it by hand.\n\n2026-08-18  Jakub Jelinek  \u003cjakub@redhat.com\u003e\n\n\tPR c++/126867\n\t* tree.cc (record_has_unique_obj_representations): Use\n\tlocation_of (const_cast \u003ctree\u003e (t)) rather than\n\tDECL_SOURCE_LOCATION (t).\n\n\t* g++.dg/cpp1z/has-unique-obj-representations6.C: New test.\n\nReviewed-by: Jason Merrill \u003cjason@redhat.com\u003e\n(cherry picked from commit 318e6a4640420d5cc213df779bf751485fa56063)\n",
